batch expanded polystyrene pre-expander machine

Vacuum drying system adopts vacuumize drying method, drying forming time short, ensure foaming more uniform & accurate and ensure clean discharging, when weighing samples will not confuse and feedback is accurate. Automatic PID adjusting and control system, temperature sensor automatic feedback. PID steam and compressed air automatic adjusting to achieve different steam temperature for different density requirement. Temperature tolerance is ±0.2℃, temperature remain stable. It achieves constant temperature and constant pressure foaming, ensure the foamed beads density evenly, foaming accuracy ±1%.

01Product Detail

Drying system can be selected according to individual users.Using the programmable control with color touch screen control, automatic sensor testing material

Second pass version is optional.Stainless steel barrel, high-quality closed constant pressure foaming pre-expander, saving about 35% energy than continuous foam pre-expander

Barrel automatic feeding using negative feed, the feed material using high pressure air. Thus shortening the materials and the material time, greatly speeding up the fat feed speed, improve production efficiency.

Using photoelectric to control material level and the capacity of foam material, getting consistent density foam beads
